Booting problem with Raspberry Pi 3

I have a Raspberry Pi 3 that is not booting with the latest Ardusub-Raspbian Image (downloaded from

The Pi boots successfully with just Raspbian, but with the Ardusub software, the ACT light just goes on but does not flicker.

Any ideas?

Please try downloading, extracting, and writing the image to the sd card again. It is possible for the image to get corrupted during these steps. I will try myself in the meantime to verify that the image online is working.


I just updated the link on that page to point to the latest ArduSub-Raspbian image.

I have confirmed that the image linked above works. If it still doesn’t work for you after going through the imaging process again, I would begin to think that your RPi 3 may have broken. You could perhaps try installing the official Raspbian image to verify what the issue is. I have had an RPi working fine for a long time, then after a simple reboot, it would not work. The ACT light just stayed lit like you describe, even with the sd card image verified to be correct on another working RPi. I ascribed the issues with that unit to ESD damage.

@jorywong - What size SD card are you using? Please note that the current image requires an SD card of 8GB or greater. If you try to flash it to a smaller SD card it will be corrupt.

@jwalser thanks so much, it’s working now!
